## Probable cause

THE NATIONAL TRANSPORTATION SAFETY BOARD DETERMINES THAT THE PROBABLE CAUSE OF THE ACCIDENT WAS THE FAILURE OF THE CAPTAIN TO USE PROPER DIRECTIONAL CONTROL TECHNIQUES TO MAINTAIN THE AIRPLANE ON THE RUNWAY.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
- Gear collapsed, landing - roll
  - landing gear,nose gear - overload

## Analysis

AT THE TIME FLIGHT 102 LANDED AT DFW AIRPORT, IT WAS RAINING AND THERE WERE NUMEROUS THUNDERSTORMS IN THE AREA. SHORTLY AFTER TOUCHDOWN ON RUNWAY 17 LEFT, THE PILOT LOSS DIRECTIONAL CONTROL WHEN THE AIRPLANE BEGAN TO WEATHERVANE AND THE CAPTAIN FAILED TO USE SUFFICIENT RUDDER CONTROL TO REGAIN THE PROPER GROUND TRACK.  THE AIRPLANE EVENTUALLY DEPARTED THE RIGHT SIDE OF THE RUNWAY.  AT THE TIME OF LANDING THE WIND (A CROSS WIND) WAS BLOWING AT 15 KNOTS WITH GUSTS APPROXIMATELY 5 KNOTS ABOVE THE STEADY WIND SPEED.
